Exercise Bike Speed Sensor Error – Causes and Repair Guide
Getting a speed sensor error on your bike's console? Our guide shows you how to find, clean, align, and test the sensor to restore your RPM reading.
Why Speed Sensors Fail
The sensor (usually a reed switch) is a delicate component. Failure is often due to misalignment, a lost magnet, a cracked sensor, or a broken wire.
Step-by-Step Troubleshooting
A checklist: 1. Find the sensor on the frame and magnet on the flywheel. 2. Check the alignment and gap (1-3mm). 3. Clean both components. 4. Trace the wire to the console and check for damage.
